INORITE!?
In this country we need to have an plastic card and a paper counterpart. ¬_¬ You need both to do your test, I did not know this and lost the paper bit ages ago, seems it happens all the time (perhaps it's an idiot filter? If it is, it doesn't work).
Haha, I knew it! My room is next to the attic storage compartment, so I'm used to treasure hunts in a forest of boxes.
Be careful though, treasure hunting can end in two ways: 1)Everything get's sorted and put back tidier than ever 2)Once treasure has been located, you get fed up and stuff everything away and run off. If you did the latter, your books might well get smooshed. Sounds like it might be new box o'clock. Is your job all sorted and secure now?
